/* KTM Recambios — sistema visual FASE 21 (D-079..D-082, `docs/features/b2b-search-ui.md` §1.3).
   Sustituye la paleta ad hoc de la FASE 14 por el diseño «B2B Recambios Moto» que el
   propietario pidió replicar. Sigue sin framework CSS (D-008): la superficie visual no lo
   justifica. Paleta clara y opaca a propósito — sin `prefers-color-scheme` (§1.3, nota roja):
   un tema oscuro a medias rompería el fondo/superficie que fija el diseño. */
